摘　　要：目的 探讨胫骨疲劳骨折的CT表现,提高其诊断及鉴别诊断水平.方法 结合文献对27例胫骨疲劳骨折的CT表现进行回顾性分析.结果 27例胫骨疲劳骨折发生于胫骨下段9例,胫骨中段6例,胫骨上段12例.CT表现：显示骨折线18例.27例均显示骨膜增生,16例呈局限性,11例呈包绕性.24例显示边缘均光整骨痂,其中17例呈丘形或梭形,7例呈不定形状或花边状.25例骨髓腔密度增高.20例周围软组织轻度肿胀.结论 CT对胫骨疲劳骨折的影像诊断具有较高的敏感性和特异性,有助于疲劳骨折的早期诊断及鉴别诊断.Objective To study CT features of fatigue fracture of tibia＂ so as to improve its diagnosis and differential diagnosis. Methods CT findings of fatigue fracture of tibia in 27 patients were retrospectively analyzed with literature review. Results In 27 patients, there were 12 patients with fatigue fracture of tibia in proximal tibia,9 patients with fatigue fracture of tibia in distal tibia and 6 patients with fatigue fracture of tibia in middle tibia. Fracture lines were showed in 18 cases. Periosteal proliferation were dis- played in 27cases. The fractures were local in 16 and enclosed in 11. The calluses appeared as smooth in 24,of them, 17 as hillock or shuttle,7 as irregullar or petal. The density of marrow cavity was increased in 25 cases. The soft tissues near to the fracture lines were slight swelling in 20 cases . Conclusion CT is sensitivity and specificity in diagnosis of fatigue fracture of tibia, and it was an important method in diagnosis and differential diagnosis of fatigue fracture of tibia.
